I recall a conversation similar to this that turned into an argument recently. Like so many do, someone knowing something without knowing why. Myself, thinking that a shaft would be the most efficient, and my friend knowing it was the most inefficient, couldnt explain why. He at the time said, as I have since then thought, that chain was more efficient. Riding our bikes with chains and belts, with equal gear ratios, i think a lot of us can concede the fact that chains transfer energy a lot quicker, and sometimes with unforgiving consistency.
Still dont understand the shaft drive idea, especially lifting the back of the wheel up.
Need a diagram for that.

I once read some engineering specs about why it was this way ... cant remember possibly due to uneven stretching etc ...

When new, Chain is almost 98%, belt is ~96% and shaft is ~90% or less.
The chain as it ages, drops below belt quite slowly ... through 1/2 its life chain is par or better than belt, but past the 95% it drops rapidly to as poor as 75 before people replace it.
Belt OTOH, is 96 when new and super stiff and slippery with oil from manufacturing, then it slowly climbs with a few 100-1000 miles to a 97 or so and stays there for a long time.
Shaft too first increases with break in, then stays there forever.
So Chain, belt, shaft when new, belt, shaft and chain when they are about to die and belt, chain and shaft @ the 1/2 way point of the chain's life.
Cool.
